Definitions Favorable To Terrorism? Sssl And Radicalization: A Case Study Approach, Jennifer Varriale Carson, Patrick Andres James

Qualitative Criminology (QC)

"Although social structure and social learning (SSSL) theory has oft been proposed as a general theory of crime, it has rarely been applied to that which qualifies as ideologically-motivated. We seek to rectify this notable gap in the research by examining the suitability of an SSSL framework to radicalization; an understudied, yet vital process to enacting evidence-based counterterrorism efforts. Utilizing a “most likely” case study approach, we find several themes consistent with SSSL principles, primarily within its social learning constructs. We conclude that SSSL does indeed offer promise for explaining all forms of crime including acts of terrorism."

An Efficient Multiple-Place Foraging Algorithm For Scalable Robot Swarms, Qi Lu

Computer Science ETDs

Searching and collecting multiple resources from large unmapped environments is an important challenge. It is particularly difficult given limited time, a large search area and incomplete data about the environment. This search task is an abstraction of many real-world applications such as search and rescue, hazardous material clean-up, and space exploration. The collective foraging behavior of robot swarms is an effective approach for this task. In our work, individual robots have limited sensing and communication range (like ants), but they are organized and work together to complete foraging tasks collectively. An efficient foraging algorithm coordinates robots to search and collect …

Implications Of Poultry Litter Usage For Electricity Production, Qiuzhou Ma, Krishna P. Paudel, Doleswar Bhandari, Chandra Theegala, Molly Cisneros

Faculty Publications

© 2019 Elsevier Ltd Poultry litter has the potential to cause water quality problems if it is not applied properly to the land as a crop nutrient. Based on the data available from a survey of Louisiana poultry producers, we find that it is not cost effective to transport poultry litter farther than 38.6 km from the production facilities for crop nutrient purposes. This limited breakeven distance restricts the movement of poultry litter and points to a need to identify an alternative disposal method. We review common methods of producing electricity from poultry litter. We identify the minimum cost solution …

The Descent Of Ancient Night Upon Heav'n: An Addition To John Milton's Paradise Lost, Book Three, Ted Snyder

The Mythic Circle

The overall concept that I work from in this addition to Paradise Lost is a rather Satanic move. Satan plays with Eve’s understanding of the Tree of Knowledge in Book 9, changing the idea of “forbidden Tree of Knowledge” to “Tree of Forbidden Knowledge.” Similarly, when I saw that God was hidden behind “unapproached light” (3.4-5), I wondered, is this unapproached or unapproachable? Milton states unapproached, which implies that it can be approached, and thus it seems that God is hiding. Also, Milton personifies the non-Biblical Chaos and his court (2.959-967), which makes me wonder, why? Milton does not specify …

The Relationship Between Socioeconomic Status And White Matter Microstructure In Pre-Reading Children: A Longitudinal Investigation, Ola Ozernov-Palchik, Elizabeth S. Norton, Yingying Wang, Sara D. Beach, Jennifer Zuk, Maryanne Wolf, John D.E. Gabrieli, Nadine Gaab

Center for Brain, Biology, and Behavior: Faculty Publications

Reading is a learned skill crucial for educational attainment. Children from families of lower socioeconomic status (SES) tend to have poorer reading performance and this gap widens across years of schooling. Reading relies on the orchestration of multiple neural systems integrated via specific white-matter pathways, but there is limited understanding about whether these pathways relate differentially to reading performance depending on SES background. Kindergarten white-matter FA and second-grade reading outcomes were investigated in an SES-diverse sample of 125 children. The three left-hemisphere white-matter tracts most associated with reading, and their right-hemisphere homologs, were examined: arcuate fasciculus (AF), superior longitudinal fasciculus …

Epidermal Growth Factor Receptor Rs17337023 Polymorphism In Hypertensive Gestational Diabetic Women: A Pilot Study, Russell S. Martins, Taimur Ahmed, Sabah Farhat, Sana Shahid, Syeda Sadia Fatima

Medical College Documents

Background: Women with gestational diabetes mellitus have an increased risk of developing gestational hypertension, which can increase fetal and neonatal morbidity and mortality. In the past decade, single nucleotide polymorphisms in several genes have been identified as risk factors for development of gestational hypertension. The epidermal growth factor receptor activates tyrosine kinase mediated blood vessels contractility; and inflammatory cascades. Abnormalities in these mechanism are known to contribute towards hypertension. It is thus plausible that polymorphisms in the epidermal growth factor receptor gene would be associated with the development of hypertension in women with gestational diabetes.
Aim: To determine whether the …

Indirect Effects In A Planktonic Disease System, Zoi Rapti, Tara E. Stewart Merrill, Liam E. Mueller-Brennan, Jerry H. Kavouras, Carla E. Cáceres

Biology Department Faculty Articles

Indirect effects, both density- and trait-mediated, have been known to act in tandem with direct effects in the interactions of numerous species. They have been shown to affect populations embedded in competitive and mutualistic networks alike. In this work, we introduce a four-dimensional system of ordinary differential equations and investigate the interplay between direct density-effects and density- and trait-mediated indirect effects that take place in a yeast parasite–zooplankton host–incompetent competitor system embedded in a food web which also includes resources and predators. Among our main findings is the demonstration that indirect effects cause qualitative and quantitative changes almost indistinguishable from …

More Homogeneous Capillary Flow And Oxygenation In Deeper Cortical Layers Correlate With Increased Oxygen Extraction, Baoqiang Li, Tatiana V. Esipova, Ikbal Sencan, Kıvılcım Kılıç, Buyin Fu, Michele Desjardins, Mohammad Moeini, Sreekanth Kura, Mohammad A. Yaseen, Frederic Lesage, Leif Østergaard, Anna Devor, David A. Boas, Sergei A. Vinogradov, Sava Sakadžić

Chemistry: Faculty Publications and Other Works

Our understanding of how capillary blood flow and oxygen distribute across cortical layers to meet the local metabolic demand is incomplete. We addressed this question by using two-photon imaging of resting-state microvascular oxygen partial pressure (PO2) and flow in the whisker barrel cortex in awake mice. Our measurements in layers I-V show that the capillary red-blood-cell flux and oxygenation heterogeneity, and the intracapillary resistance to oxygen delivery, all decrease with depth, reaching a minimum around layer IV, while the depth-dependent oxygen extraction fraction is increased in layer IV, where oxygen demand is presumably the highest. Our findings suggest that more …

Kinship Ties Across The Lifespan In Human Communities, Jeremy Koster, Dieter Lukas, David Nolin, Eleanor Power, Alexandra Alvergne, Ruth Mace, Cody T. Ross, Karen Kramer, Russell Graves, Mark Caudell, Shane Macfarlan, Eric Schniter, Robert Quinlan, Siobhan Mattison, Adam Reynolds, Chun Yi-Sim, Eric Massengill

ESI Publications

A hypothesis for the evolution of long post-reproductive lifespans in the human lineage involves asymmetries in relatedness between young immigrant females and the older females in their new groups. In these circumstances, inter-generational reproductive conflicts between younger and older females are predicted to resolve in favor of the younger females, who realize fewer inclusive fitness benefits from ceding reproduction to others. This conceptual model anticipates that immigrants to a community initially have few kin ties to others in the group, gradually showing greater relatedness to group members as they have descendants who remain with them in the group. We examine …

Structural Racism And Odds For Infant Mortality Among Infants Born In The United States 2010, Roman Pabayo, Amy Ehntholt, Kara L. Davis, Sze Yan Liu, Peter Muening, Daniel Cook

Department of Public Health Scholarship and Creative Works

Abstract

OBJECTIVES:

While ecological studies indicate that high levels of structural racism within US states are associated with elevated infant mortality rates, studies using individual-level data are needed. To determine whether indicators of structural racism are associated with the individual odds for infant mortality among white and black infants in the US.

METHODS:

We used data on 2,163,096 white and 590,081 black infants from the 2010 US Cohort Linked Birth/Infant Death Data Files. Structural racism indicators were ratios of relative proportions of blacks to whites for these domains: electoral (registered to vote and voted; state legislature representation), employment (civilian labor …

The Dynamic Roles Of Red Blood Cell In Microcirculation, Sitong Zhou

Theses

Erythrocytes (otherwise known as red blood cells (RBCs)), are the most common cell type in the body. They are responsible for oxygen (O2) transportation as well as carbon dioxide (CO2) exchange. Different from most cells, red cells have no nuclei in mammals due to the enucleation during the maturation. The structure of erythrocytes was shown to have a phospholipid bilayer membrane, membrane proteins and cell skeleton. It provides the stability that RBCs need for the circulation in the body systems. Also, this well-established structure makes it possible for them to accomplish ion and gas exchange, which therefore keeps the osmolality …

Transforming Trauma: Resilience And Healing Through Our Connections With Animals, Philip Tedeschi, Molly Anne Jenkins

Purdue University Press Books

Have you ever looked deep into the eyes of an animal and felt entirely known? Often, the connections we share with non-human animals represent our safest and most reliable relationships, offering unique and profound opportunities for healing in periods of hardship. This book focuses on research developments, models, and practical applications of human-animal connection and animal-assisted intervention for diverse populations who have experienced trauma. Physiological and psychological trauma are explored across three broad and interconnected domains: 1) child maltreatment and family violence; 2) acute and post-traumatic stress, including military service, war, and developmental trauma; and 3) times of crisis, such …

Design Of A Canine Inspired Quadruped Robot As A Platform For Synthetic Neural Network Control, Cody Warren Scharzenberger

Dissertations and Theses

Legged locomotion is a feat ubiquitous throughout the animal kingdom, but modern robots still fall far short of similar achievements. This paper presents the design of a canine-inspired quadruped robot named DoggyDeux as a platform for synthetic neural network (SNN) research that may be one avenue for robots to attain animal-like agility and adaptability. DoggyDeux features a fully 3D printed frame, 24 braided pneumatic actuators (BPAs) that drive four 3-DOF limbs in antagonistic extensor-flexor pairs, and an electrical system that allows it to respond to commands from a SNN comprised of central pattern generators (CPGs). Compared to the previous version …

Role Of Host Cell Β-Catenin During Toxoplasma Gondii Infection, Cameron H. Ranken

Biology ETDs

The microbial pathogen Toxoplasma gondii is an intracellular protozoan that actively invades host cells and simultaneously creates a specialized parasitophorous vacuole within which the parasite lives and replicates. The parasite molecular machinery that drives establishment of the intracellular niche is relatively well known. However, it is now emerging that Toxoplasma exploits less well-understood host cell components to enable successful infection. Here, we examined the role of host Wnt/β-catenin during T. gondii infection. Using human fibroblasts and a mouse dendritic cell line, we found that infection with Toxoplasma stimulated both upregulation and nuclear localization of β-catenin. Using a transwell experimental approach, …

Ecological And Morphological Response Of Rodents To Environmental Change Over The Late Quaternary, Catalina Tomé

Biology ETDs

The rapid progression of modern climate change is already altering ecosystems worldwide. By employing the fossil record, we can investigate how animals responded to past climatic changes and biodiversity loss. The paleontological record of the late Quaternary (past ~22000 years) encompasses a period of considerable environmental change in North America. Rising temperatures and climatic fluctuations are coupled with the extinction of the majority of large bodied mammals on the landscape. The combination of climate and extinction events led to changes in vegetation and community structure which likely affected the resources available and interactions between the remaining mammals within communities. Here, …

Cartographies Of Precarity: The Cultural Politics Of Filipina And Mexican Migrant Domestic Workers, Maria Eugenia López-García

American Studies ETDs

This dissertation examines the cultural politics of migrant domestic work in the 2000s within popular culture, mass media, contemporary art, and grassroots national organizing. While scholars and activists have identified that migrant domestic workers are the hidden backbone of the U.S. economy, dominant cultural and social narratives reinforce the racialized and gendered logics of capitalism that work to devalue domestic work as informal, disposable and precarious. It was not until after the struggle of domestic workers achieved recognition through the ratification of the International Labor Office of Convention 189 in July 2011 that this labor sector gained more intense media …

Temporal Patterns In Multi-Modal Social Interaction Between Elderly Users And Service Robot, Ning Wang, Nuovo A Di, Angelo Cangelosi, Ray Jones

School of Nursing and Midwifery

Abstract Social interaction, especially for older people living alone is a challenge currently facing human-robot interaction (HRI). There has been little research on user preference towards HRI interfaces. In this paper, we took both objective observations and participants’ opinions into account in studying older users with a robot partner. The developed dual-modal robot interface offered older users options of speech or touch screen to perform tasks. Fifteen people aged from 70 to 89 years old, participated. We analyzed the spontaneous actions of the participants, including their attentional activities and conversational activities, the temporal characteristics of these social behaviours, as well …

Development Of Threshold Levels And A Climate-Sensitivity Model Of The Hydrological Regime Of The High-Altitude Catchment Of The Western Himalayas, Pakistan, Muhammad Saifullah, Shiyin Liu, Adnan Ahmad Tahir, Muhammad Zaman, Sajjad Ahmad, Muhammad Adnan, Dianyu Chen, Muhammad Ashraf, Asif Mehmood

Civil and Environmental Engineering and Construction Faculty Research

Water shortages in Pakistan are among the most severe in the world, and its water resources are decreasing significantly due to the prevailing hydro-meteorological conditions. We assessed variations in meteorological and hydrological variables using innovative trend analysis (ITA) and traditional trend analysis methods at a practical significance level, which is also of practical interest. We developed threshold levels of hydrological variables and developed a non-parametric climate-sensitivity model of the high-altitude catchment of the western Himalayas. The runoff of Zone I decreased, while the temperature increased and the precipitation increased significantly. In Zone II, the runoff and temperature increased but the …

The Chaotic Domestic: Tracing Affect In Representations Of Nation, Class, And Gender In Eighteenth-Century Laboring-Class Women’S Writing, Kelly J. Hunnings

English Language and Literature ETDs

My dissertation traces a term I call the “chaotic domestic” in the writing of a collection of eighteenth-century women laboring-class writers: Mary Barber, Mary Collier, Mary Leapor, Ann Yearsley, and Janet Little. The chaotic domestic in the hands of these writers is multi-layered and affect-driven, focusing as they do on issues regarding nation, class, and gender. As both a poetic trope and the seeming natural and dynamic state of the domestic sphere, the image of the domestic that this set of writers represents and defines is turbulent, unruly, and one that deals with the tangled web of local and global, …

Presenting The Good Mother: Experiences Of Canadian Adolescent Mothers Living In Rural Communities, Karen A. Campbell, Corinne Hart

The Qualitative Report

Adolescent mothers and their children are at risk for suboptimal health outcomes making adolescent motherhood a public health concern. However, the experiences of rural-living adolescent mothers are not well understood. Using Lieblich, Tuval-Mahiach, and Zilber’s (1998) narrative methodology approach, the experiential accounts of three rural-living adolescent mothers was explored. Reflecting Goffman’s (1959) presentation of self, the findings of this study revealed how adolescent mothers attempted to construct and present their notion of being a good mother, while coping with complicating rural factors. The need to present as a good mother, the lack of anonymity associated with rural living, and geographical …
